Abstract
Nanocomposite PVA/PEG/PVP/SnS2/V films were created via thermolysis and casting procedures. X-ray diffraction and scanning electron microscope devices were applied to inspect the microstructure parameters of the nanofiller and its distribution throughout the blend matrix. The thermal stability of the blend was improved upon loading it with the nanofiller. The variations in optical parameters and emitted colors of the blend upon doping are explored. The optical band gap was effectively lowered (5.19 -> 3.14 eV), while the n and epsilon(r) values increased. All films displayed nearly a normal dispersion feature. As the percentage of SnS2/V increased in the polymer blend, its nonlinear optical parameters effectively improved. The FL intensity was greatly lowered with increasing the nano-SnS2/V dopant in the blend matrix, nominating the formed blends for photocatalytic applications.
